The Top Components: What are roofs in the US, made off?

09.05.2023 Admin 108

When it comes to roofing materials, Canadian homeowners have a variety of options to choose from. Each material serves a specific purpose and is crucial for the overall integrity of the roof. In this section, we'll discuss the most common roofing materials used in Canada. 


Shingles are one of the most popular and widely used roofing materials in Canada. They come in various materials such as asphalt, wood, and metal, providing homeowners with a range of choices based on their budget, climate, and desired aesthetic. 

Roofing Papers and Underlayment 

Roofing papers, also known as an underlayment or felt, play a vital role in providing a waterproof barrier between the roof deck and the shingles. This material ensures that any water that may seep through the shingles is effectively redirected away from the roof structure, preventing leaks and moisture damage. 

Roof Flashing 

Roof flashing is a critical component in preventing water intrusion at various roof intersections and penetrations. Typically made of metal or plastic, flashing is installed around chimneys, vents, and roof valleys to seal gaps and direct water flow away from vulnerable areas. 

Nails and Fasteners 

Using the right nails and fasteners ensures that roofing materials are securely attached to the roof, preventing them from being blown off or damaged during harsh weather conditions. It's essential to choose the appropriate type and size of nails, as well.

Any other component we can add?

Indeed, there are a few more vital components of a roof in Canada that we should discuss. Let's dive in and explore some of these essential parts that help protect your home from the elements. 

The Roof Deck 

The roof deck is the foundation of your roofing system. It is the structural layer that supports the weight of the entire roof and serves as a base for all the other roofing components. Typically made of plywood or OSB (oriented strand board), it is crucial to ensure your roof deck is in good condition to prevent sagging or leaks. 

The Top Components: What are roofs in Canada made of?

In Canada, roofs are made of various components that work together to shield homes from elements such as rain, snow, and wind. The main components of a roof include:

1.    Decking: This is the foundation of the roof and is the surface where all other components are attached. Decking is usually made of wood or metal and needs to be in good condition to prevent leaks and sagging.

2.    Underlayment: A protective layer is installed between the decking and shingles, underlayment provides a barrier against water and ice, preventing leaks and damage to the deck. Some popular underlayment options you can trust, are:

·         Owen Corning’s Rhino Roof.

·         Bakor Blueskin RF200.

·         GAF FeltBuster.

·         Bakor Eaveguard Self-Adhered.

3.    Flashing: Installed around penetrations like chimneys, vents, and skylights, flashing is typically made of metal and directs water away from these vulnerable areas.

4.    Roof deck: The structural layer that supports the weight of the entire roof and serves as a base for all the other roofing components. Canadian roofs are typically made of plywood or oriented strand board (OSB).

5.    Nails and fasteners: Using the right type and size of nails and fasteners ensures that roofing materials are securely attached to the roof, preventing them from being blown off or damaged during harsh weather conditions. A common size for roofs in Canada is a 12-gauge shank and a 3/8-inch diameter head.

Understanding these main components of a roof is crucial for identifying and addressing potential issues before they become costly repairs.

What are the most common types of roofing materials used in Canada?

The most common type of roofing material in Canada is asphalt shingles. They're popular due to their affordability, durability, and ease of installation. Available in various colors and styles, asphalt shingles can complement any home's exterior design.

Other commonly used roofing materials in Canada include:

1.    Metal roofing: Durable and long-lasting, metal roofs can withstand extreme weather conditions and come in different styles, such as panels or shingles.

2.    Cedar shingles or shakes: Known for their natural and rustic look, cedar shingles or shakes are relatively expensive but can last up to 30 years if maintained properly.

3.    Synthetic materials: Materials such as plastic or rubber can imitate the look of other roofing materials, such as slate and tile, at a more affordable cost.

4.    Flat roofing: Typically used on commercial buildings, flat roofing materials such as rubber and modified bitumen can also be used on residential homes with flat or low-sloped roofs.

Roof Maintenance and Repairs

Regular roof inspections and maintenance can extend the life of your roof and save you money in the long run. Look for signs of damage like missing or curled shingles, cracked or rusted flashing, and water stains on your ceiling or walls.

Minor asphalt shingle repairs can be performed by many homeowners themselves, but consulting with a roofing professional for more complex issues or if you're unsure about the proper repair method is recommended.

Three Things to Look For in roofing materials before buying: manufacturer warranty, installation requirement, and the brand you're buying from.

When choosing the right roofing materials, there are several factors to consider. To ensure that you get the best value and performance from your investment, here are three things you should look for in roofing materials before making a purchase:

1.    Manufacturer Warranty: Look for a manufacturer warranty that covers a wide range of issues such as material defects and workmanship errors, and ensure that the warranty period is long enough to provide you with peace of mind.

2.    Installation Requirements: Proper installation is essential for the longevity and performance of your roof. Research the installation requirements for the roofing material you're considering, and ensure that your contractor is knowledgeable and experienced in that specific material.

3.    Brand Reputation: Consider purchasing from a reputable brand with a solid track record, positive customer reviews, and a commitment to sustainability and innovation. A reputable brand is more likely to provide quality materials and stand by its products when issues arise.

By taking the time to assess these factors, you can make an informed decision when purchasing roofing materials and protect your investment for years to come.
